What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Wilmington, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at May 14, 1:36 PM EDT, 2 hours 18 minutes earlier.

Area forecast discussion, May 14, 1:36 PM EDT, 2 hours 18 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
136 PM EDT FRI MAY 14 2010

.SYNOPSIS...
A COLD FRONT WILL SLOWLY PUSH THROUGH THE AREA TODAY INTO THIS
EVENING. HIGH PRESSURE WILL BUILD ACROSS THE GREAT LAKES SATURDAY
AND SUNDAY. LOW PRESSURE WILL MOVE INTO THE OHIO VALLEY SUNDAY
NIGHT AND MONDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A COLD FRONT WAS LOCATED FROM CLE...TO CVG...THEN TO SDF. THIS
FRONT WILL CONTINUE TO SLOWLY SAG SOUTHEAST TODAY. INSTABILITY
WILL OCCUR ALONG AND JUST AHEAD OF THE FRONT WITH THE HIGHEST
AMOUNTS LOCATED ACRS THE FAR SOUTHEAST. THIS FRONT...COUPLED WITH
PERHAPS A WEAK UPPER LEVEL DISTURBANCE...WILL RESULT IN SOME
SHOWERS AND THUNDERSTORMS. THERE IS A SMALL CHANCE THAT A FEW
STORMS MAY REACH SEVERE LIMITS IN THE SE CWFA THIS AFTN. HAVE
UPDATED ZONES/GRIDS TO REMOVE POPS FROM THE NORTHWEST. WILL LIKELY
NEED ANOTHER UPDATE TO SHAVE OFF MORE OF THE REGION FROM THE
CHANCES OF SHOWERS/THUNDERSTORMS ONCE THE TRAILING EDGE OF THE
INSTABILITY AXIS IS MORE CERTAIN.  MOS BLEND LOOKED REASONABLE
FOR HIGHS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/...
COULD STILL BE SOME ACTIVITY IN THE SOUTHEAST DURING THE EVENING.
BUT THAT WILL MOVE OFF AS THE FRONT FINALLY MAKES IT ALL OF THE
WAY THROUGH THE FORECAST AREA. RIDGING FROM HIGH PRESSURE BUILDING
INTO THE GREAT LAKES WILL RESULT IN DRY CONDITIONS LATE FRIDAY
NIGHT INTO SATURDAY EVENING.

COULD START TO SEE SOME MOISTURE RIDE OVER THE RIDGE LATE SATURDAY
NIGHT INTO SUNDAY. THIS WILL PROVIDE INCREASED CLOUD COVER AND
SOME SHOWERS ARE NOT OUT OF THE QUESTION. ELEVATED INSTABILITY IS
FORECAST TO SPREAD INTO THE AREA LATE SUNDAY. SO SOME THUNDERSTORMS
WILL ALSO BE POSSIBLE.

DID NOT VARY SIGNIFICANTLY FROM MOS TEMPERATURES.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
SHORT WAVE SLOWLY TREKKING ACROSS THE COUNTRY WILL INTERACT WITH A
NORTHERN STREAM SYSTEM. THIS WILL RESULT IN AN UPPER LOW CLOSING
OFF TO THE WEST OF THE AREA AND THEN MAKING ITS WAY THROUGH THE
MIDDLE OF THE WEEK. TROUGHING MAY EVEN LINGER INTO THURSDAY.
COPIOUS MOISTURE WILL GET DRAWN INTO THE AREA AHEAD OF THIS
SYSTEM. SO EXPECT SHOWERS TO BE LIKELY FROM LATE SUNDAY NIGHT INTO
MONDAY EVENING. EXTENSIVE CLOUD COVER MAY LIMIT DESTABILIZATION.
SO ONLY FORECAST A CHANCE OF THUNDERSTORMS. CHANCE OF
PRECIPITATION WILL PERSIST INTO TUESDAY NIGHT BEFORE DRYING SETS IN.

HIGHS WILL BE RUNNING BELOW NORMAL ESPECIALLY ON TUESDAY AND
WEDNESDAY WHEN THE UPPER LOW IS IN CLOSEST PROXIMITY. CLOUDS AND
LOW LEVEL MOISTURE SHOULD PREVENT TEMPERATURES FROM FALLING TOO
FAR AT NIGHT.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
A COLD FRONT WILL CONTINUE TO MOVE SLOWLY SOUTHEAST AWAY FROM THE
TAF SITES THIS AFTERNOON. SURFACE HIGH PRESSURE WILL THEN BUILD
INTO THE REGION TONIGHT...SETTLING ACROSS THE OHIO VALLEY ON
SATURDAY. EXCEPT PERHAPS SOME MVFR RIVER FOG AT KLUK BETWEEN 09Z-
15Z...VFR CONDITIONS ARE EXPECTED.

.OUTLOOK...SHOWERS AND THUNDERSTORMS WITH MVFR CIGS/VSBYS POSSIBLE
SUNDAY NIGHT THROUGH TUESDAY NIGHT. MVFR CIGS POSSIBLE ON
WEDNESDAY.

&&

.ILN WATCHES/WARNINGS/ADVISORIES...
OH...NONE.
KY...NONE.
IN...NONE.
